I was able to apply for a DL here in Michigan by providing my passport, i94, and the notices of action as a proof of residency.
Yesterday I passed my road test and I'll head to the Secretary of State later today, so I'll update if I had any issues.
Did you get any updates? My standalone approval notice was sent 4/21 and my status remains the same. According to the notice they take 1 to 2 weeks to produce the card.
